Description

  The present invention relates to a tube clogging removal device for removing clogging of a flexible suction / discharge pipe that discharges debris with suction air, a suction / discharge type excavator equipped with this tube clogging removal device in a switchable manner, and the suction / discharge The present invention relates to a foundation vertical pile construction system equipped with a type excavator.

  The inventor of the present application is a suction discharge type drilling tool for drilling a vertical hole for a foundation pile as a foundation such as a steel tower of a high-voltage cable without entering a vertical hole drilled by a person, and this drilling. A basic vertical pile construction system using tools is proposed in Patent Document 1 (many parts common to FIGS. 4 and 5) and Patent Document 2 (many parts common to FIG. 6).

  In this tube clogging removing device 60, a propeller 51 is attached to the rear end portion of a cylindrical body 53 and a pair of arms 54 are rotatably attached to each other, and both are connected by a shaft 52. The brush 55 is attached to the pipe PA, and is installed so as to be movable by the driven wheel 56 of the pipeline PA. The device 60 is moved by the water flow W at a speed slower than the water flow W through the brake cable 58 by the operation of the brake winch installed on the ground. Thus, the propeller 51 is rotated with a rotational force corresponding to the difference between the two speeds, and the brush 55 is rotated with the rotational force to clean the inner surface of the pipe PA.

  Thus, according to the device 60, since the structure using water current energy is used as compared with the self-propelled cleaner, the mechanism of the device becomes simple, compact and inexpensive, and the operation adjusts the feeding speed of the braking winch or the like. Therefore, it is very easy to handle, there are few on-shore facilities, and the cost is reduced (paragraph [0014] of Patent Document 3).

  However, the clogging removing device 60 shown in FIG. 9 can clean and remove clogs in a substantially straight line, but is bent by a flexible suction / discharge pipe that the inventor intends to use. The case could not be used to clear the clog. Also, it seemed that there was insufficient power to remove the clogs that were firmly attached to the inner wall of the pipe.

Embodiment 1

  FIG. 1 is an exploded perspective view showing an example of the tube clog removing device of the present invention, FIG. 2A is an external perspective view showing an assembled state of the tube clog removing device of FIG. 1, and FIG. It is an external appearance perspective view of a part.

  1 is a tube clog removing device 10 that removes clogging of a flexible suction / discharge pipe 39 (see FIG. 3) that discharges debris with suction air. An auxiliary ring 27 shorter than the main body cylinder 21 is provided.

  The main body cylinder 21 is provided at an axially central portion of the outer periphery of the main body cylinder 21, and includes an outer protrusion ring 21a having an outer diameter slightly smaller than the inner periphery of the target pipe and a small width. The outer diameter is an outer diameter with the outer protrusion ring 21a as a center so that it contacts the inner circumference of the pipe 39 when the target pipe 39 is bent at the maximum. Identical.

  As shown in the figure, the main body cylinder 21 is hollow, passes suction air, pivotally supports a rotor blade 22 rotated by the suction air, and the rotation shaft 23 is on the side opposite to the auxiliary ring 27. It extends from the main body cylinder 21, and a clogging scraper blade 24 is provided in the extended portion 23 a. The main body cylinder 21 is sucked air for discharging debris and is strongly pulled in the suction discharge pipe 39 in the upstream direction, and the rotor blades 22 are also strongly rotated.

  In addition, the auxiliary ring 27 and the main body cylinder 21 are connected by a free joint 26, and the auxiliary ring 27 is provided with a pulling wire 28 (see FIG. 3). The auxiliary ring 27 and the pulling wire 28 are inserted into the clogged pipe 39 in this order while adjusting the feed length, and the clogging blade 24 removes the clogging.

  A ventilation flange 21b provided with a vent hole as much as possible is fixed to both ends on the inner peripheral side of the main body cylinder 21 by a method such as welding or screwing. A rotating shaft 23 is rotated at the center of the ventilation flange 21b. The bearing 21c which supports is fixed.

  The rotated blade 22 supported in the main body cylinder 21 efficiently captures the suction air on the wing cylinder 22a long enough to be accommodated in the main body cylinder 21 and the outer periphery of the wing cylinder 22a. In this example, the rotating blade body 22b that rotates strongly is provided so as to divide the outer periphery into four equal parts. The blade cylinder 22a is fixed to the rotary shaft 23 by screw means, but both may be fixed by other methods such as a spring pin.

The rotating shaft 23 is supported by a pair of concentric bearings 21c, rotates smoothly, and transmits the powerful rotational force received by the rotating blade 22 to the scraping blade 24.
A T-shaped connecting body 25 is screwed to the ventilation flange 21b of the main body cylinder 21 by the upper side of the T-shape, and an auxiliary ring is connected to the distal end side of the connecting body 25 via a free joint 26. 27 are mutually rotatable with respect to the main body cylinder 21, and the inclination between each other is connected in a three-dimensional manner without restriction.

  The auxiliary ring 27 has a cylindrical shape and is provided with a stop plate 27a so as to bisect its inner periphery. A U-shaped stop ring 27b through which the pulling wire passes is provided at the center of the stop plate 27a. It has been.

  The completed state of the tube clogging removing device 30 is clearer from FIG. The material of each part of the tube clogging removing device 30 may be steel, stainless steel, or aluminum as long as it can cope with strength.

  As shown in FIG. 2 (b), the free joint 26 includes a one-side joint ring 26a that is rotatably connected to the distal end side of the leg portion of the connecting body 25 in the direction of arrow A, and an auxiliary ring 27 in the direction of arrow B. The other side coupling ring 26b is rotatably connected, and both ring parts are fitted into the other ring part, and the auxiliary ring 27 is freely rotatable with respect to the pulling wire 28. The degree of freedom of the relative angular relationship between the main body cylinder 21 and the auxiliary ring 27 is very large.

  FIG. 3 is a view showing a usage mode of the tube clogging removing apparatus of FIG. In addition, about the part already demonstrated from this, the same code | symbol is attached | subjected and duplication description is abbreviate | omitted.

  The suction / discharge pipe 39 shown in FIG. 3 is flexible and can be bent to the extent shown in the drawing, but a reinforcing rib is formed on the outer periphery, and a cross-section is obtained even when a considerably low-pressure suction air passes inside. The shape does not collapse.

  The suction and discharge pipe 39 is sucking and discharging debris, but as shown in the drawing, clogging B is generated in the upper portion, and the debris suction and discharge capability is reduced. Therefore, from the upstream side, the tube clogging removing device 30 is inserted in the order of the scraping blade 24, the main body cylinder 21, the auxiliary ring 27, and the pulling wire 28 as illustrated.

  At this time, the suction air flow in the suction / discharge pipe 39 is somewhat reduced due to the clogging B, but the pipe clogging removing device 30 formed of iron can be strongly suctioned against its weight, so that the traction The wire 28 is extended from a powered winch or the like, and the device 30 is moved to the beginning while resisting pulling by suction. .

  Here, the main body cylinder 21 is substantially in contact with the inner periphery of the suction / discharge pipe 39 by the external projection ring 21a, but the other part has an outer diameter enough to pass even if the suction / discharge pipe 39 is bent to some extent. Further, since the auxiliary ring 27 connected via the free joint 26 is connected to the auxiliary ring 27 with the pulling wire 28 in a state where the outer periphery thereof faces the inner periphery of the suction / discharge pipe 39 almost evenly, Even if the suction discharge pipe 39 has a certain bend, the scraping blade 24 can reach the position of the clog B of the bent suction discharge pipe 39 by extending the pulling wire 28.

  In order to reach the target position while pulling the clogging removal device 30 in the suction / discharge pipe 39 having such a bend, as described above, the auxiliary ring 27 having the free joint 26 interposed therebetween is used. The inventor of the present application has found that it is necessary to connect the pulling wire 28 after trial and error, and this has resulted in this idea.

  Therefore, according to the tube clog removing device 30 of the present invention, a simple structure can be obtained even when a strong clog is generated in the flexible suction discharge pipe for discharging the debris with suction air and there is a certain bend. The clogging can be removed. In particular, as shown in FIG. 3, when the traction wire 28 is connected to the auxiliary ring 27 and the traction wire 28 is pulled, the suction / discharge pipe is curved to such an extent that the traction wire 28 contacts the inner periphery of the suction / discharge pipe 39. Can also be used.

  FIG. 4 shows an example of the suction / discharge type excavator of the present invention equipped with the tube clogging removing device of FIG. 1, (a) is a conceptual longitudinal section of the main part, and (b) is (a) ) Is an external view as viewed from the excavation tip side, FIG. 5A is a top view thereof, FIG. 5B is a front view thereof, and FIG. 5C is a side view thereof.

  This suction-and-discharge type excavator 10 is used by being attached to a hydraulic construction machine installed on the ground or an earth retaining body at the bottom of the earth retaining method, and is mainly used for a vertical hole that serves as a foundation mine for steel towers and large buildings. Used for excavation.

  The suction discharge type excavating tool 10 includes a rock excavation part 1 for dredging the bedrock with a vibrating rock rod 1 a, a cylindrical excavation part 2 that is driven to rotate around the rock formation part 1, and a rock formation part 1. The main body base 3 with the excavation part 2 installed at the center, the crushing part 4 provided between the main body base 3 and the excavation part 2, the rocks excavated by the rock formation part 1, excavated by the excavation part 2, and crushed by the crushing part 4 And debris suction means 5 for sucking and discharging debris in the excavated portion 2.

  In addition, the suction / discharge-type excavator 10 is installed in the main body base 3 and can be attached / detached to / from a hydraulic construction machine or the like (not shown). And a unit attaching portion 7 for attaching to the housing. The main material of each part from the rock formation part 1 to the unit attachment part 7 is steel unless otherwise specified.

  The peridotite portion 1 includes the above-described peridotite rod 1a and a main body 1b that vibrates the peridotite rod 1a in the vertical direction B of FIG. 4A by hydraulic pressure, and is generally commercially available. Things can be adopted.

  The peridotite rod 1a can be attached to and detached from the main body 1b, and an optimum one can be used according to the target of the peridotite.

  In addition, the rock formation part 1 can be attached or detached to the main body base 3, and can also be removed when it is not necessary to rock a hard bedrock. In this case, the weight of the suction / discharge-type excavator 10 can be reduced by the weight of the rock portion 1.

  The excavation part 2 is supported by the main body base so as to be rotatable around the peridotite rod 1a, and receives the rotational driving force from the rotational driving means 6, and the outer cylindrical part co-rotating concentrically with the inner cylindrical part 2a 2b, a plurality of crosspieces 2c connecting the inner cylindrical portion 2a and the outer cylindrical portion 2b, and a plurality of rock excavation tips 2d provided on the front side of the crosspiece 2c.

  In addition, the excavation part 2 includes a plurality of peripheral excavation tips 2e provided at the front peripheral end of the outer cylindrical part 2b, and the rear end part of the rotating outer cylindrical part 2b near the main part 3 of the main body base 3. Two upper and lower rotary bearings 2h that rotatably support the outer peripheral rib 2f provided so as to cover the front side, the auxiliary excavation tip 2g provided at appropriate positions of the plurality of crosspieces 2c, and the inner cylindrical portion 2a with respect to the main body base 3. 2i.

  The inner cylindrical portion 2a transmits the rotational driving force from the rotational driving means 6 to the crosspiece 2c and the outer cylindrical portion 2b, and enables rock excavation by the rock excavation tip 2d and the peripheral excavation tip 2e provided thereon. It is formed with a strong wall thickness.

  The inner diameter of the inner cylindrical part 2a is an inner diameter that maintains a gap that does not hinder the rock rock rod 1a from vibrating when the rock rock part 1 is attached to the outer diameter of the rock rock rod 1a. . As shown in FIG. 4 (a), the protruding length of the inner cylindrical portion 2a from the main body base 3 spans a plurality of crosspieces 2c from the outer front end of the inner cylindrical portion 2a to the inner periphery of the front end of the outer cylindrical portion 2b. In some cases, the length is longer than the protruding length of the front end circumference of the outer cylindrical portion 2b so as to be a central convex.

The outer cylindrical portion 2b is cylindrical, but when excavated by the suction / excavation type excavator 10, the excavation surface is covered by the front end circumference and a closed space is formed by the excavation portion 2 and the excavation surface, as will be described later. In addition,
The earth and stone sucking means 5 also plays a role of allowing the suction force to be suitably exerted.

  In this example, the plurality of rock excavation tips 2d provided on the front side of the plurality of cross beams 2c that are centrally convex are, as shown in the drawing, two cross frames 2 that are positioned to divide the circumference into two equal parts. The top of the rock excavation tip 2d is disposed so as to form a conical spiral as a whole.

  Each rock excavation tip 2d is not provided directly below, but is provided so as to be inclined at a certain angle in the rotation direction T (shown in FIG. 4B) of the excavation unit 2. Therefore, the excavated bedrock is directed to the inner side of the excavation unit 2 as the excavation unit 2 rotates in the rotation direction T.

  The peripheral excavation tip 2e excavates rocks existing in the vicinity of the peripheral part of the excavation part 2 so that the excavation part 2 can enter and enter the rock and excavation part to be excavated as a whole. That is, if there is no such peripheral excavation tip 2e and only the front peripheral end of the cylinder, the above-mentioned airtight effect is obtained, but the front peripheral end is blocked by a hard rock or the like, and the excavation part 2 does not enter. Therefore, this peripheral excavation tip 2e is provided.

  The outer peripheral rib 2f covers the outer front end of the main body base 3 and prevents the suction of air from between the rear peripheral end of the excavating part 2 and the front peripheral end of the main body base 3 as much as possible, and debris sucking means The suction force by 5 reaches the crushed debris in the excavation part 2. The auxiliary excavation tip 2g is provided for auxiliary excavation.

  The two rotary bearings 2h and 2i are fixed to the base of the main body and reliably support the inner cylindrical portion 2a by its inner ring. In particular, the upper rotary bearing 2h is constituted by a thrust rotary bearing, and the rock portion 1 It can withstand the upward thrust load that is highly likely to be applied to the inner cylindrical portion 2a during the seismic dredging.

As described above, the main body base 3 serves as a structural base for installing the rock formation portion 1, the excavation portion 2, and the unit attachment portion 7 on the outside thereof, and is a circular box body. As shown in FIG. 4A, a gear train 6r that constitutes the rotation driving means 6 is accommodated therein.
A hydraulic motor 6 a serving as a drive source for the rotational drive means 6 is further installed outside the main body base 3, and passes through the main body base 3 at an appropriate position of the main body base 3, inside the excavation section 2. An open discharge pipe 5a is provided.

The crushing portion 4 includes a set of two backward crushing tips 4a provided from the back surface of the crosspiece 2c toward the rear, and a forward crushing tip 4b provided from the main body base portion 3 toward the front. .
As shown in FIG. 4 (a), the backward crushing tip 4a and the forward crushing tip 4b have a portion overlapping each other in the rotational axis direction (vertical direction in the figure) of the excavation unit 2, while When the crushing tip 4a rotates, the forward crushing tip 4b is configured to pass between the pair of the backward crushing tips.

  Therefore, a large piece of rock that has been dredged in the dredged rock part 1 also has the effect of gravity and co-rotates in a state where it is stretched over two rotating crushing tips 4a, and the two crushing crushes. It will crash into the forward crushing tip 4b protruding in the middle of the tip 4a, and it will be crushed into smaller rock fragments.

  That is, the crushing part 4 composed of the backward crushing chip 4a and the forward crushing chip 4b has a crushing function of crushing a large piece of rock crushed by the rock formation part 1 into smaller pieces.

  The debris suction means 5 includes an excavation part 2 that rotates while maintaining airtightness with respect to the main body base 3 by the outer peripheral ribs 2f, and a discharge provided through the main body base 3 toward the inside of the excavation part 2. And a tube 5a. A suction air V indicated by a white arrow in FIG. 4A is supplied to the discharge rod 5a. As shown in FIG. 5, a storage tube 5b is provided at a position adjacent to the discharge rod 5a. The discharge rod 5 a and the storage rod 5 b are positioned so as to be switched in the suction opening of the main body base 3.

  The rotation driving means 6 includes the above-described hydraulic motor 6a and a gear train 6r that transmits the rotational driving force of the hydraulic motor 6a to the inner cylindrical portion 2a at the center of the excavating portion 2, and the gear train 6r includes: A driving gear 6b directly connected to the output shaft of the hydraulic motor 6a, an intermediate large gear 6c meshing with the driving gear 6b, an intermediate small gear 6d concentrically with the intermediate large gear 6c, and an intermediate small gear 6e meshed with the inner cylindrical portion 2a. A fixed driven gear 6e is provided.

  As the drive source of the rotational drive means 6, here, hydraulic pressure is used from the point that hydraulic pressure is used in the rock formation part 1 and there is a hydraulic pressure source nearby, and a large and large driving force can be obtained. If the condition is satisfied, it may be pneumatic or electric.

  Here, a normal spur gear train is used as the gear train 6r of the rotation drive means 6, but the present invention is not limited to this as long as a desired reduction ratio can be obtained in a limited space. For example, a gear train of a worm and a worm wheel gear train, an internal gear attached to the inner side of the outer cylindrical portion 2b, and a pinion gear corresponding thereto may be used.

  The unit mounting portion 7 will be described with reference to FIG. 5. The unit mounting portion 7 is installed on the back surface of the main body base 3 so as to sandwich the rock portion 1 between the rock portion 1, the suction port 5a, and the installation portion of the hydraulic motor 6a. A base portion 7a and a general-purpose mounting portion 7b that is detachably connected to the mounting base portion 7a and includes a coupling hole 7c that can be attached and detached at a tip portion of a hydraulic construction machine or the like.

  With this configuration, the suction / discharge type excavator 10 is attached to the tip of a heavy construction machine or the like, and in principle, the direction of the tip of the suction / discharge type excavator 10 is downward, that is, the direction of excavation of the vertical hole. It can be used to drill excavation objects including hard rock.

  At this time, even if there is a hard rock that is difficult to be excavated by the rock excavation tip 2d of the excavation part 2, the dredged rock can be formed by the rock rod 1a that vibrates strongly before and after the excavation part 1. It is in a state of being broken into rock pieces in the range restricted to the outer peripheral edge of the excavation part 2 to the maximum extent.

  This large rock fragment is directed to the inside of the excavation section 2 by a rock excavation tip 2d provided so as to scoop up the facing rock fragments with respect to the rotational traveling direction of the excavation section 2, and between the back side portion of the crosspiece 2c and the main body base 3 In the internal space of the excavation part 2, the crushing part 4 is crushed into smaller rock fragments by the interaction of the backward crushing chip 4a and the forward crushing chip 4b.

  The excavation and crushing of the rock is also performed by the rock excavation tip 2d, the peripheral excavation tip 2e, and the auxiliary excavation tip 2g of the excavation part 2. Then, it is sucked and discharged out of the unit 10.

  Thus, according to this suction / discharge type excavator 10, the operator can dig the entire unit 10, press against the object to be excavated, the seismic motion of the rock formation portion 1, the rotation operation of the excavation portion 2, and the suction to the debris suction means 5. Even if there is a hard bedrock, the drilling of the vertical hole can be carried out continuously without approaching the excavation part simply by operating the air supply.

  Since the dust generated at this time is sucked and discharged by the debris suction means 5, the problem of environmental deterioration near the excavation site due to the dust is also solved. That is, according to the suction and discharge type excavation tool 10 of the present invention, it is possible to excavate hard rock mass while efficiently and easily discharging generated materials such as debris and dust generated by excavation to the ground.

  In addition, the effect of the suction discharge type excavating tool 10 of the present invention that enables two functions, such as excavation work including such hard rock mass and suction and discharge of debris generated by excavation, with one hydraulic construction machine, etc. In general, the excavation site can be widely used, and many hydraulic construction machines can be arranged. The excavated rocks can be discharged and removed with a hydraulic excavator. In some cases, it doesn't feel much.

  However, when drilling a vertical hole as the foundation hole of a steel tower for high-voltage power transmission lines in a mountainous area, it is difficult to secure a wide flat area as a drilling site. Therefore, the effect of the suction discharge type excavating tool 10 that enables excavation and discharge of debris is great. In addition, the suction discharge type excavating tool 10 of the present invention further includes the rock formation portion 1 and the crushing portion 4, and even if it is a hard bedrock, it can rock and crush and excavate the excavated debris. The effect is even greater.

  Further, according to this suction / discharge type excavator 10, as will be described later, the depth of the vertical hole is increased, and in other cases, manual work at the bottom of the hole or change of the tip excavator is necessary. In addition, even when it is impossible to discharge debris with a hydraulic excavator, it is possible to operate from the ground or from the top of the vertical hole, excavation work including hard rock, and suction and discharge of debris generated by excavation The industrial significance of the effect of the present invention, which enables these two functions with a single hydraulic construction machine, is even greater.

  The suction / discharge-type excavator 10 has a turning means 8 for rotating the attachment base 7a side of the suction / discharge-type excavator 10A with respect to the universal attachment 7b between the attachment base 7a of the attachment 7A and the universal attachment 7b. Is further provided.

  The turning means 8 incorporates a hydraulic motor or an electric motor, can rotate only the rotating portion 8b relative to the fixed portion 8a, and can be fixed so that both of them do not rotate at a position of a desired rotation angle. Is.

  Such a turning means 8 can change the orientation of the suction / discharge type excavator 10 with respect to the hydraulic construction machine even if the hydraulic construction machine or the like to which the suction / discharge type excavator 10 is attached does not rotate. It functions as a turning means.

  According to the swivel means 8 as described above, when the hydraulic pump 6a protrudes from the main body base 3 due to the location of the main body base 3 as in the suction discharge excavator 10 of the present invention, the wall of the vertical hole When excavating along the sway, there will be excavation as much as this bulge, but the swiveling means 8 only swivels the mounting base 7a side of the suction / discharge type excavator 10 so that this bulge does not get in the way. Can do.
